Auxiliary resonant snubber inverters (RSIs) have been proposed as a solution of demands for inverter, which are high efficiency and low EMI. In RSI, zero voltage switching (ZVS) on the inverter main switches is achieved by use of the auxiliary circuit; however, additional conduction loss increases simultaneously. The operating frequency of the auxiliary circuit in RSI can be reduced to a half of switching...
A novel converter using three switching devices, which has a DC input and two single-phase AC outputs, is proposed. A PWM control scheme for the proposed converter is also described in this paper. Moreover, simulation verification of the proposed converter is conducted. As a result, it is shown that the proposed converter can convert electric power bidirectionally among a DC terminal and two AC terminals...
